fr-Loon oF ARTIFICIAL STONE. l

Patented June 19,1906.

To all Lch/m,4 it may concernf 'Be it known that I, PAUL LANGGUTH, a citi at Charlottenburg, inthe Province of Brandenburg, Germany, have invented Acertain new and useful Improvements Floors of `Artificiall .Stone and I do hereby declare the following to be a full, clear, and exactdescri tion of the invention, such aswill enable ot ers skilled IO in the art to which it appertains to make and use the'same. Y .A l

My invention relates to and has for its object a jointless composite artificial-stone loor made out of a combination' of Wooddust 0r the like. asbestos, magnesite, and a binding-lye ofcertain salts, such as chlorid h vof magnesiumor the like.

In order to avoid the disadvantages of artificialv stone or cement floors previously in 20,

use, which alwaysare laid on a ycement or Concrete foundation and which have the disadvantages that the racks which form in the concrete foundation are continued or transmitted through to' the artificial-'stone floor,

I make my new floor outlof three layers of dierent materials. The up ermost la er consists ofthe said artiiicia stone.'v hc layer under this which joins the uppermost layer ,with theconcrete foundation 1s very similar to the well-known heat-isolat' Ina-1 terial andis 'an elastic material conta' cork chips or cuttings.' In the manufacture of this cork concrete, chips or cuttings of cork are mixed with any suitable bin' material, so that the mass may be forme into a layer of .light and cheap' elastic material which will stretch to alimted extent longi- .tudinally. The\third layer consists of ta paper or the like and lies directly on the con-` crete foundation. .f Thislast layeris not a continuous layer,l"-\but `discontinued and 'broken a't many places, and atthese breaks' the elastic intermediate so-called. cork con# crete comes. into immediate contact with the concrete foundation.

I illustrate different possible ways of making such a iioor in the accompanying draws, 'nwhichf- .l s y igure 1 is a vertical section through the floor, which is composed of three layers and the concrete foundation. is a plan of 4the'same in which the differentlayers are arrangement the same manner of represenbroken away' at different points, so Athat all are shown. 3 and 4 are-likewise a section through and plan of a secondrnethod of vuppermost artificial stone.'

s is seen from F ig.` 2, the paper layer (l has a great number of perforations or holes which have very different 4shapes,1so1'ne, for example, being represented circular and some square. As is readily perceptible, the intermediate layer f, which the paper directly covers, comes into contact at these laces where the holes are with the concrete 1 oundation and unites fast with it. .,At'those places, however, where the paperv is such a union 1s prevented, and in consequenceof this a union of the artificial-stone layer with through the kagency of the intermediate corkconcrete layer at those places where the holes are. In consequence, the ;`pos' sibilitv arises that the concretefoundationfcanfshift or move in a certain degree relatively tothe artificial-stone la er, or,l contrariwisetfhe latter can move re atively to the foundation,

since' the intermediate layer isl elastic( and a union does not take place over the .whole` surface,.but only at single places. y

Itis not necessary for the paper to be laid out in one continuous or perforated .'s'heet; but, on the other hand, itis advantageous fpr a largefnumber of pieces of paper toybe distributed onv the foundation, so that 'definite spaces. are left clear between t mtervenin l them, whic suffice for the union of the intermediate layer with the foundation. Figs. 3 and 4 show such a' Hoor in which separate sheets of paper d of square shape are employed,

the concrete-foundat.iona-only takes place i IOC wlnch areso arranged on the foundation a i that a net-like system of strips g is formed between the. sheets of paper, in which places the union takes lace. v i

In the metho of erection shown in` Fig. 5 paper sheets of circular form are employed, While the method'shown in Fig. 6 the paper sheets are arranged in long strips d, so that equally long strips g are left. clear between them. The distance between the separate IIC holes and the" distance between the strips` which are not covered by the paper7 respectively, as well as the size of the holes and the breadth of the strips,respectively`-, must be so chosen thatthe artificial-stone layer isjoi'ned sufficiently securely with the foundation.

Both the distance between' the separate holes or strips and the area of the places notcoveredby paper standin an interdependent re-.

lationshiptoward one another, as with a defi` nite distance a corresponding area must be The advantage of my new floor is that `the said ,elastic intermediate connecting-layer deadens the sound in eachplace, and although the layer extends from end to end the union only takes place at single places, and' to have the union at separate definitelyarranged placesneed only arrange the paper in a definite manner;- but only layers ofY quite uniform pattern 4need be traced out.

What I claim 1s.- y 1'.. A. ilooring comprising a foundation, a thin separating-sheet restingl on the said foundation and provided with interruptions asuperposed layer'or1 elastic concrete adher-v ing to the said foundation only wherein direct contact with its surface at the said interruptions, and a top layer of hard surface material.

2. Jointless floor of artificial stone consist-v ing of three layers lying on a concrete founlss dation of which one'is continuous artificial stone, another is an equally continuous elastic intermediate layer o.cork concrete and another is a frequently-interrupted layer 'of isolating-paper which l'ies directly on the ing of three layers lying on 4foundation and which allowsthe intermedi- .ate layer to join with the concrete foundaing of three layers lying` on a concrete foundation of which one' is continuous artificial` stone, another is an equally continuous elastic intermediate layer of cork concrete and another is -a layer ofisolatingpaper which liesdirectly on the, foundation and which consists of separate sheets ,of Voptional .form which are not joined to one another.

5. Jointless iloor of artificial stone consisting of three-layers lying on- 'a concrete foun# dation of which one is a continuous artificial stone, another-1s an equally continuous elastlc intermedlate layer of cork concrete and another is a layer of isolating-paper which lies directly on lthe foundationand' which Aconsists ofseparate strips with intervening interruptions left free between them.

In ltestimony whereof I affix my signature in presence of two witnesses.
